Gr 6–9—A detailed, thoroughly researched, and engaging story about Virginia Hall, a much-forgotten but vitally important figure in U.S. and British history. Hall served as a spy, first for the British and then for the Americans, aiding the French Resistance in Nazi-occupied France during World War II. Mitchell pulls readers into Hall's story in a compelling narrative that does not skimp on facts. There is plenty of historical detail given as context, to frame Hall's life as a spy, but also to inform readers about life in occupied France and give a fuller picture of the war. This book includes a thorough bibliography filled with primary and secondary source material, detailed endnotes, and photo credits. The author also included lots of primary source information and quotes from Hall's niece, Lorna Catling.
